  2. Kyrgios 6-4 4-6 3-6 6-1 Humbert

    Peter Odgers

    When Kyrgios is in this mood, he is tough to live with. And for the second time this year, these two will head to a fifth set.

  3. Game and fourth set - Kyrgios

    Kyrgios 6-4 4-6 3-6 6-1 Humbert

    They played each other at the Australian Open in January and that went five sets, this one's gone five too.

    Peter Odgers

    What a shot to break, and what a fourth set this has been. He has always been a man for the big stage.

  5. Kyrgios break and serves for the set

    *Kyrgios 6-4 4-6 3-6 5-1 Humbert

    The crowd will be thinking it's a shame we've got a curfew of 11pm as they're loving this and fully involved.

    Kyrgios produces a brilliant game to take the break and is now one service hold from taking it to five.

  6. You can't fault the effort from Kyrgios today, he's sprinting around the court and, considering, this is his first match in five months, this is a great effort.

    He's at break point to possible move 5-1 ahead in the fourth.

    Adrenaline is a wonderful substance - and Kyrgios is riding it right now.

    Peter Odgers
    BBC Sport commentator

    Kyrgios is full of adrenaline. The momentum is absolutely with him at the moment.

  9. Kyrgios 6-4 4-6 3-6 4-1 Humbert*

    Kyrgios, the great entertainer, has those that are still in Court One very much on his side with a brilliant service game as he harnesses the crowd's energy to pull clear in the fourth.

  10. *Kyrgios 6-4 4-6 3-6 3-1 Humbert

    Peter Odgers
    BBC Sport commentator

    Would you believe it?

  11. Kyrgios breaks

    *Kyrgios 6-4 4-6 3-6 3-1 Humbert

    But another double fault gifts Kyrgios the break and this could well be going to a decider and be finished on Wednesday.

  12. A double fault from Humbert gives Kyrgios a third chance to break in this game. He couldn't take the first two opportunities...

  13. Kyrgios 6-4 4-6 3-6 2-1 Humbert*

    Peter Fleming
    Seven-time Grand Slam doubles champion on BBC One

    Humbert is certainly not lacking confidence at the moment.

  14. Kyrgios gets a Hawk Eye decision go his way and he's getting the crowd pumped up as Humbert has to save a break point, which he does.

  15. Kyrgios 6-4 4-6 3-6 2-1 Humbert*

    You never know what you're going to get with Kyrgios. He's been talking to himself constantly for the last 30 minutes and keeps trying the tricks of the between the legs shot. It's not worked once, but the crowd are loving it.

    Then moments later he shows his serving prowess to grab a vital hold.

  16. *Kyrgios 6-4 4-6 3-6 1-1 Humbert

    Humbert does well to stop the Kyrgios charge gaining pace with a good hold.

  17. Tomorrow's order of play

    Defending champion Novak Djokovic will open play on Centre Court tomorrow.

    His match against Kevin Anderson - which was the final at SW19 a few years back - will be followed by Britain's Katie Boulter, who takes on second seed Aryna Sabalenka.

    Finally, Andy Murray will close out the day's play against Oscar Otte of Germany.

    Elina Svitolina is first on Court One, followed by British number one Dan Evans.

    Five-time champion Venus Williams closes the day out against Ons Jabeur.

  18. Kyrgios 6-4 4-6 3-6 1-0 Humbert*

    The pep talk has clearly worked for Kyrgios, who blasts down four aces in a row. What a way to start the fourth.

    A reminder, the play will end at 23:00 BST so we might not see the end of this one today.

  19. "This guy plays monstrous, huge," says Kyrgios talking to himself, the camera, the world, whoever's listening in between the third and fourth sets.

  20. Game and third set - Humbert

    Kyrgios 6-4 4-6 3-6 Humbert

    And that's a 2-1 lead for Humbert as he holds his serve to take the third set. Kyrgios had played an inbetweener on the last point of the set, but then misses a volley close to the net.
